We have Azure container instance with IP, which is updates each time after restart. Is far as I understand there is no possibility to use static IP for this. Is there A way to use FQDN? Or prevent it from changing or what is the best variant to fix it?

    Hello @Oleksandr Kucherenko

    thank you for your question to use static IP with ACI you can go with one of those solutions as below:

    1- Expose a static IP address for a container group

    2- Configure a single public IP address for outbound and inbound traffic to a container group

    3- Configure a NAT gateway for static IP address for outbound traffic from a container group

    4- Deploy a container group with custom DNS settings here what are you looking for.

    There is a quick-start in the docs that show how to leverage a Static IP via deploying an additional service; An Azure Application Gateway.
    https://video2.skills-academy.com/en-us/azure/container-instances/container-instances-application-gateway

    You can create Azure Container Instances with a FQDN though, which is much simpler and results in a FQDN like; your-aci-dns-name.westeurope.azurecontainer.io

    This is the command you'd use in the Azure CLI;

    az container create --resource-group myResourceGroup --name mycontainer --image mcr.microsoft.com/azuredocs/aci-helloworld --dns-name-label your-aci-dns-name --ports 80

    If you are wanting to update an existing container instance then you just run the same command;

    # Update DNS name label (restarts container), leave other properties unchanged
az container create --resource-group myResourceGroup --name mycontainer \
    --image nginx:alpine --dns-name-label myapplication
